Description

Technical Field

[0001] The invention relates to the technical field of target materials, in particular to a Z-shaped spliced ​​target material. Background Art

[0002] The target material is the target material for high-energy particle bombardment and is also one of the main materials for preparing thin films. It is mainly used in integrated circuits, flat panel displays, solar cells, and smart glass. Sputtering is one of the main technologies for preparing thin film materials. Its principle is to use the ions generated by the ion source to form a high-speed ion beam after vacuum acceleration, and then bombard the solid surface. The ions and the solid surface exchange kinetic energy, causing the atoms on the solid surface to leave the solid and deposit on the substrate surface. The bombarded solid is the sputtering target. The target material is a consumable. During use, as the material is continuously consumed, when it reaches a certain level, it needs to be replaced.

[0003] At present, most of the existing target materials are of one-piece design. During actual magnetron sputtering, the trajectory of the magnetic lines of force has a certain positionality, so that only a small area of ​​the entire target material is used.

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] Embodiment 1:

[0043] See also Figure 1 to Figure 2 A Z-shaped spliced ​​target material comprises a bottom plate 1 and an adjusting device 2 symmetrically arranged on the upper end of the bottom plate 1, wherein the adjusting device 2 is fixedly connected to a back target 3 at the proximal end thereof, the back target 3 is a hollow structure, a plurality of target materials 4 are spliced ​​on the side wall of the back target 3 to form a target surface, and the target material 4 and the back target 3 are connected by a locking device 5;

[0044] The upper end surface of the bottom plate 1 is symmetrically provided with an arc-shaped slideway 11 , and the bottom of the arc-shaped slideway 11 is evenly provided with limiting holes 12 along the arc direction thereof.

[0045] The adjusting device 2 comprises a sliding disk 21, which is slidably arranged at the bottom of the arc-shaped slideway 11, and symmetrically provided with insertion holes, in which a pin rod 22 is inserted, and the lower end of the pin rod 22 extends into the limiting hole 12, and a threaded rod 23 is fixedly connected to the upper end of the sliding disk 21, and a slide cylinder 25 is sleeved on the threaded rod 23, and the slide cylinder 25 has symmetrical upper and lower sides screwed with adjusting screw buckles 24 for fixing the slide cylinder 25, and a cross bar 26 is fixedly connected to the middle of the side wall opposite to the slide cylinder 25, and the end of the cross bar 26 away from the slide cylinder 25 is fixedly connected to the back target 3, and the slide cylinder 25 and the threaded rod 23 are clearance-fitted.

[0047] Embodiment 2:

[0048] The technical solution is basically the same as that of the first embodiment, see Figures 1 to 10 The difference is that: the side wall of the back target 3 close to the target material 4 is evenly provided with slide grooves 31 from top to bottom, the slide grooves 31 are arranged in pairs and a through groove 32 is provided on the back target 3 between each pair of slide grooves 31, and positioning holes 33 are symmetrically provided in the slide grooves 31 on the upper and lower sides of the through groove 32, and a number of heat dissipation holes 34 are provided on the side walls of the back target 3 facing the adjustment device 2 on both sides, and threaded holes 35 are provided on the side wall of the back target 3 away from the target material 4 and corresponding to the middle of the through groove 32, and sliding rods 36 are symmetrically provided at the positions of the back target 3 facing the through groove 32, and the sliding rods 36 are slidably connected to the locking device 5.

[0049] An extension rod 41 is fixedly provided on the middle part of the side wall of the single target material 4 near the back target 3, and the end of the extension rod 41 away from the target material 4 is fixedly connected with a clamping head 42, and the clamping head 42 extends to the through groove 32. Positioning rods 43 corresponding to the number of positioning holes 33 are fixedly provided on the side wall of the target material 4 around the extension rod 41, and the end of the positioning rod 43 away from the target material 4 abuts against the positioning hole 33.

[0050] The cross section of the target material 4 is in a "Z" shape so that the two ends of the target material 4 form a proximal surface 44 and a distal surface 45 from the back target 3. In the horizontal direction, the proximal surface 44 of the target material 4 and the distal surface 45 of the target material 4 adjacent thereto are connected to form a transverse target surface through a clamping assembly 46. In the vertical direction, two adjacent target materials 4 are tightly attached to each other to form a vertical target surface. The transverse target surface and the vertical target surface together constitute the target surface.

[0051] The clamping assembly 46 includes a proximal clamping plate 461, which is fixedly installed on the proximal surface 44, and the end of the proximal clamping plate 461 away from the proximal surface 44 is fixedly connected to a rectangular strip 462, and a clamping groove 463 is opened in the middle of the rectangular strip 462, and a distal clamping plate 464 is fixedly connected to the distal surface 45, and the end of the distal clamping plate 464 away from the distal surface 45 is fixedly connected to an arc-shaped connecting portion 465, and the end of the arc-shaped connecting portion 465 is fixedly connected to a clamping column 466, and the clamping column 466 is installed in the clamping groove 463.

[0052] A magnet block 47 is fixedly mounted on the side wall of each target material 4 near the back target 3 , and magnet blocks 47 with opposite magnetic properties are arranged on the adjacent side walls of two adjacent target materials 4 .

[0053] During the specific operation, two target materials 4 are first placed alternately up and down manually so that the proximal end surface 44 of one target material 4 is parallel to the distal end surface 45 of the other target material 4, and then the two target materials 4 are moved horizontally so that the clamping column 466 and the clamping groove 463 are aligned, and then the two target materials 4 are pushed up and down so that the clamping column 466 moves into the clamping groove 463, and finally the upper and lower end surfaces of the two target materials 4 are at the same height, and the target surfaces of the two target materials 4 are also in the same vertical plane, thereby completing the splicing between the two target materials 4, and then the required target materials 4 are spliced ​​together according to the above method to form a complete target surface, until the required target surface is larger than the area formed by the required sputtering trajectory;

[0054] After the above steps are completed, the positioning rod 43 of the entire target material 4 is inserted into the slide groove 31 and moved horizontally along the slide groove 31 to a suitable position. At this time, the positioning rod 43 will be aligned with the positioning hole 33. The entire target material 4 is gently pressed toward the back of the target 3 manually to insert the positioning rod 43 into the corresponding positioning hole 33. The magnet blocks 47 between the two target materials 4 will attract each other, so that the left and right target materials 4 fit tightly together.

[0055] Embodiment three:

[0056] The technical solution is basically the same as that of the first embodiment, see Figure 2 , Figure 6 , Figure 8 and Fig.10The difference is that: the locking device 5 includes a T-shaped locking rod 51, the T-shaped locking rod 51 is penetrated in the threaded hole 35, the end of the T-shaped locking rod 51 located outside the back target 3 is fixedly connected with an ear plate 52, a threaded section 53 is opened in the middle of the T-shaped locking rod 51, the threaded section 53 is connected with the threaded hole 35, and the end of the T-shaped locking rod 51 located inside the back target 3 is rotatably connected with a locking head 54, and the locking head 54 and the sliding rod 36 are slidably matched.

[0057] The locking head 54 includes a rubber segment 541. The end of the T-shaped locking rod 51 located inside the back target 3 is rotatably connected to the rubber segment 541. Both ends of the rubber segment 541 are fixedly connected to "L"-shaped locking plates 542. The "L"-shaped locking plates 542 and the clamping head 42 abut against each other. A flexible layer 543 is arranged between the two "L"-shaped locking plates 542, and the flexible layer 543 is wrapped around the outside of the clamping head 42.

[0058] During specific operation, after the positioning rod 43 is inserted into the corresponding positioning hole 33, the ear plate 52 and the T-shaped locking rod 51 are manually rotated forward. Due to the existence of the sliding rod 36, the sliding rod 36 will provide a certain support force to the locking head 54 and limit it at the same time, so the locking head 54 will not rotate. At this time, the T-shaped locking rod 51 rotates and drives the locking head 54 to move toward the target material 4. Finally, the clamping head 42 will move to the inside of the "L"-shaped locking plate 542 and squeeze the flexible layer 543. At this time, the flexible layer 543 continuously covers both sides of the clamping head 42, and the squeezing force will make the "L"-shaped locking plates on both sides The end of 542 away from the rubber segment 541 approaches the clamping head 42 and contacts the extension rod 41. At this time, the ear plate 52 and the T-locking rod 51 are rotated in the opposite direction. At this time, the T-locking rod 51 will move in the direction away from the target material 4. At the same time, the T-locking rod 51 will pull the rubber segment 541 and cause it to deform away from the target material 4. The deformation will drive the "L"-shaped locking plate 542 to slide relative to the extension rod 41. Finally, the "L"-shaped locking plate 542 abuts against both sides of the clamping head 42, and cooperates with the reaction force of the flexible layer 543 to achieve the purpose of locking and fixing the target material 4. At this point, the installation process of the target material 4 is completed.

[0059] The working principle of the present invention when in use:

[0060] One: First, manually place two target materials 4 in an alternating manner up and down, so that the proximal end surface 44 of one target material 4 is parallel to the distal end surface 45 of the other target material 4, then move the two target materials 4 horizontally to align the clamping column 466 with the clamping groove 463, and then push the two target materials 4 up and down to move the clamping column 466 into the clamping groove 463, and finally the upper and lower end surfaces of the two target materials 4 are at the same height, and the target surfaces of the two target materials 4 are also in the same vertical plane, thereby completing the splicing between the two target materials 4, and then splicing the required target materials 4 according to the above method to form a complete target surface, until the required target surface is larger than the area formed by the required sputtering trajectory;

[0061] 2. After the above step 1 is completed, the positioning rod 43 of the entire target material 4 is inserted into the slide groove 31 and moved horizontally along the slide groove 31 to a suitable position. At this time, the positioning rod 43 will be aligned with the positioning hole 33. The entire target material 4 is gently pressed toward the back of the target 3 manually to insert the positioning rod 43 into the corresponding positioning hole 33. The magnet blocks 47 between the two target materials 4 will attract each other, so that the left and right target materials 4 are tightly fitted.

[0062] 3. When the positioning rod 43 is inserted into the corresponding positioning hole 33, the ear plate 52 and the T-shaped locking rod 51 are first rotated forward manually. Due to the existence of the sliding rod 36, the sliding rod 36 will provide a certain support force to the locking head 54 and limit it at the same time, so the locking head 54 will not rotate. At this time, the T-shaped locking rod 51 rotates and drives the locking head 54 to move toward the target material 4. Finally, the clamping head 42 will move to the inside of the "L"-shaped locking plate 542 and squeeze the flexible layer 543. At this time, the flexible layer 543 continuously covers both sides of the clamping head 42. At the same time, the squeezing force will make the "L"-shaped locking plates 542 on both sides move away from the end of the rubber segment 541. The clamping head 42 approaches and contacts the extension rod 41, and the ear plate 52 and the T-shaped locking rod 51 are rotated in the opposite direction. At this time, the T-shaped locking rod 51 will move in the direction away from the target material 4. At the same time, the T-shaped locking rod 51 will pull the rubber segment 541 and deform it away from the target material 4. The deformation will drive the "L"-shaped locking plate 542 to slide relative to the extension rod 41. Finally, the "L"-shaped locking plate 542 abuts against both sides of the clamping head 42, and cooperates with the reaction force of the flexible layer 543 to achieve the purpose of locking and fixing the target material 4. According to the above steps, each locking device 5 and the corresponding clamping head 42 are locked in turn, thereby completing the installation process of the target material 4;

[0063] Fourth: The position of the target surface is determined by manually rotating the position of the sliding plate 21 so that the target surface faces the ion emitter, and then the adjusting screw 24 is rotated to drive the slide 25, the cross bar 26, the back target 3 and the target material 4 to move up and down, so that the middle of the target surface and the ion emitter are at the same level, and then the ion emitter is started to complete magnetron sputtering;

[0064] Five: When the target surface of the target material 4 is consumed to a certain extent and needs to be replaced, the ear plate 52 and the T-shaped locking rod 51 are manually rotated forward, and the locking device 5 will release the locking effect on the chuck 42. The targets 4 can be manually removed and rearranged, and then installed according to the above steps to perform magnetron sputtering again.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
